They are. It's basically just a tendon, though.

Himalayan Chews
 

My little girl LOVES himalayan chews! She has only had bully sticks before so she was a little skeptical about them but now she'll leave a bully stick lay is she has one of these around. They are a little more pricey than the bully sticks I buy ( I get the bully sticks off the westbrookdog site) and I buy the himalayan chews from an awesome all natural dog supply store in my town. My only problem with them, and it may just be my odd little Emma's chewing, but they seem to get flakey when she's chewing and there's little flakes of stinky cheese on the floor! lol

I ordered two small pkgs of the Himalayan chews for my girls and one antler to try out. I have been looking for something for my girls to chew on that would last longer than bully sticks and be good for them too.Thanks for the post.

LOL! I haven't noticed that happening with Addie, but I have been having problems with her chewing them to death. The small size is the best, I think for our pups, but I feel like there's not that much for our pups to chew on before we have to throw them away so they don't swallow them and choke. :/

Let us know how your girl likes them!
One pack of Himalayans lasted me about two weeks. I've already ordered another two. :)

Oh then I am glad I ordered 2! LOL;)

how small are the Himalayan dog chews?
I am thinking of getting a medium size
the smallest size looks really short. It looks like they would be able to swallow them whole. Polo normally chews a six inch bully stick.
I tried the Antlerz and Polo liked it for 2 days and now he won't touch it:(
I am thinking he would like the Himalayan dog chews better:D

I ordered the small pack of Himalayan Chews on ebay I hope Polo likes them:D
they do last longer then bully sticks?

Whoops! I didn't see your last comment! I would think the small ones are the best. They're about 3 1/2 inches to four inches. I've had some that were longer, but none that were shorter. I do have to throw away a portion of the Chews after Addie has at it for a while because I don't want her to choke on it. You just have to watch your pup and determine when that is. The problem with the medium one is that there's only one per pack while there are several per pack of the small ones. I feel like you get more for your money with the small ones. There's also only one chew for the large size. I'm not sure if it would be worth the money for that one, but I'm also concerned about it being too large for Addie. Perhaps someone who has tried the Chews in the medium or large size could comment?

The Chews are like a rock, so I would think with a dog that loves Bully Sticks and Chews, the Chews would last longer. It's hard for me to tell, though, because Addie really really loves the Chews and doesn't care much for the Bully Sticks. Addie will nibble on the chew for hours, but she'll only touch the Bully Sticks for ten minutes and then get bored. But she still manages to go through Bully Sticks pretty quickly.
